Info:
Time to let go of my extra stash of Kefs...

I have 5 total. 4 used. 1 unused. Someone could make a killer home audio setup with these mated to a nice midwoofer. Or build a full 5.x setup with these.


These are truly some of, if not the best Concentric mids made. Kef's engineering on these is superb. They are intended to be used as a midrange/tweeter and most of the models using these drivers employ a 500hz crossover to keep cone motion minimal.

I have tested these drivers myself and you can find my test data here:
Kef: http://medleysmusings.com/kef-r300-midrange-drive-unit-testing/


Basic measurements are as follows:
~130mm OD
~110mm mounting diameter
~90mm mounting depth



Condition:

These were high passed at 500hz on the midrange and about 2.8khz on the tweeters.



Asking Price:

(4) Used - $220/each shipped, CONUS.
(1) BNIB - $255shipped, CONUS.
(3) trim rings - $15/each shipped, CONUS.

I can work a package deal if you're interested. For example:
For 3: $570 shipped
For 5 + trim rings = $1k shipped.


Contact:

Email: hardisj(at)gmail(dot)com and PM are fine.



Photos:

A couple shots of a used pair I have with and without the trim rings.
